CUTTING GLASS. If glass be held in one hand under water, and a pair of scissors in the other, it may be cut like brown paper; or if a red hot tobacco pipe be brought in contact with the edge of the glass, and afterwards traced on any part of it, the crack will follow the edge of the pipe. CUTTING OF TEETH. Great care is required in feeding young children during the time of teething. They often cry as if disgusted with food, when it is chiefly owing to the pain occasioned by the edge of a silver or metal spoon pressing on their tender gums. The spoon ought to be of ivory, bone, or wood, with the edges round and smooth, and care should be taken to keep it sweet and clean. At this period a moderate looseness, and a copious flow of saliva, are favourable symptoms. With a view to promote the latter, the child should be suffered to gnaw such substances as tend to mollify the gums, and by their pressure to facilitate the appearance of the teeth. A piece of liquorice or marshmallow root will be serviceable, or the gums may be softened and relaxed by rubbing them with honey or sweet oil. D. DAIRY. In a publication intended for general usefulness, the management of the dairy, the source of so many comforts, demands some attention, in addition to the information conveyed under various other articles, connected with this interesting part of female economy. A dairy house then ought to be so situated that the windows or lattices may front the north, and it should at all times be kept perfectly cool and clean. Lattices are preferable to glazed lights, as they admit a free circulation of air; and if too much wind draws in, oiled paper may be pasted over the lattice, or a frame constructed so as to slide backwards and forwards at pleasure. Dairies cannot be kept too cool in the summer: they ought therefore to be erected, if possible, near a spring of running water. If a pump can be fixed in the place, or a stream of water conveyed through it, it will tend to preserve a continual freshness and purity of the air. The floor should be neatly paved with red brick, or smooth stone, and laid with a proper descent, so that no water may stagnate: it should be well washed every day, and all the utensils kept with the strictest regard to cleanliness. Neither the cheese, rennet, or cheesepress, must be suffered to contract any taint; nor should the churns be scalded in the dairy, as the steam arising from the hot water tends greatly to injure the milk. The utensils of the dairy should all be made of wood: lead, copper, and brass are poisonous, and cast iron gives a disagreeable taste to the productions of the dairy. Milk leads in particular should be utterly abolished, and well-glazed earthen pans used in their stead. Sour milk has a corroding tendency, and the well known effects of the poison of lead are, bodily debility, palsy, and death. The best of all milk vessels are flat wooden trays about three inches deep, and wide enough to contain a full gallon of milk.
